| 摘 要： | 运用ICP仪对南京市15种主要绿化树木的叶片吸收吸附铅、锌的能力进行了研究。结果表明:15种树木叶片对铅、锌具有一定的吸收净化能力,并依污染物和树种的不同差异明显。在被研究的15个树种中,对铅吸收量较高的树种是雪松和圆柏,对锌吸收量较高的树种是杨树。对铅吸附能力强的树种是雪松,对锌吸附能力强的树种是海桐。叶片吸收和吸附铅的能力强的树种是雪松,叶片吸收和吸附锌的能力强的树种是杨树。最后,通过综合分析得出,杨树和雪松叶片中重金属铅和锌的累积量,可作为铅锌污染监测和评价的重要依据。

| Abstract: | 15 afforestation trees in Nanjing were studied in absorbing and adsorbing Pb and Zn by ICP instrument.The results showed that the trees could absorb Pb and Zn pollutants in different extent depending on pollutants and tree species.Among 15 studied tree species,Cedrus deodara and Sabina chinensis had high absorption capacity to Pb,Populus Canadensis Moench to Zn;Cedrus deodara had higher adsorption capacity to Pb,and Pittosporum tobira to Zn.As for the absorption and adsorption of leaves to Pb,Cedrus deodara... |
